I didn't see any topic about this and figured this was as good a place as any to post about it..

I've used this for 40 years and never had an upper cylinder engine issue of any kind..always had peak performing injectors and clean valves..(compression testing)...I just wanted to share, not trying to sell anyone on the this product, but I swear by it..I have only added it to my gas..6oz. to every 10 gallons.
